The IBEX SCIENCES Sacrum and Coccyx anatomical features are integrated directly into their 85cm Life-Size Flexible Spine Model with Pelvis bundle. This medical-grade replica provides an accurate, tactile demonstration of the specialized bones forming the posterior pelvic wall and the terminal anchor of the human vertebral column. [1, 2, 3, 4, 5]
Key Bony Landmarks & Structures Represented
- Sacral Base and Apex: The broad, superior platform articulates directly with the fifth lumbar vertebra (L5 joint), while the inferior apex tapers down to meet the tailbone. [1, 2, 3]
- Fused Sacral Segments (S1–S5): Explicitly displays the fused structural remnants of the 5 individual sacral vertebrae that unify in early adulthood. [1, 2]
- Sacral Foramina: The model features four pairs of anterior and posterior openings allowing the escape paths for the sacral spinal nerve branches to be easily traced. [1, 2]
- Median Sacral Crest: Tactile ridges on the posterior side accurately mimic the fused spinous processes found on natural human bones. [1, 2]
- The Coccyx (Tailbone): Features the terminal cluster of tiny, partially fused vertebrae attached via a modeled sacrococcygeal symphysis joint. [1, 2, 3]
Integrated System Features
- Sacral Plexus & Nerve Exits: Shows branching nerve roots traveling down from the cauda equina through the sacral canal and exiting the sacral hiatus. [1, 2]
- Pelvic Girdle Articulation: The sacrum is securely mounted to the left and right coxal (hip) bones at the auricular surfaces, demonstrating the structural mechanics of the sacroiliac (SI) joint. [1, 2]
- High-Resiliency Cast: Formulated from industrial-grade, washable PVC polymer designed to withstand heavy, repetitive handling in chiropractic and orthopedic teaching settings. [1, 2]
